Weighted diffuser sticks are perfect for aerating and mixing in ponds, tanks, dugouts or anywhere that a need for dependable micro-bubbles are required.

If you are building your own DIY aeration system these diffuser tubes are ideal. They come in three confirgurations: a single diffuser tube, a single diffuser tube mounted on a heavy duty poly plate or a dual diffuser stick assembly with two diffusers on a large poly plate. All diffusers are self weighting so they will sink to the bottom. The diffuser sticks on plates come equipped with a barbed line connector to accept 3/8" airline.

If you have a different size air hose you can simply get a MPT x HB poly hose insert to match your hose ddiameter. The single diffuser stick has a 3/4" MPT inlet only to allow for retro-fitting your Airmax KorAir diffuser or to build your own custom diffuser according to your hose lengths.

This KoiAir™ PTFE stick is attached to a heavy duty polyplastic base to reduce the amount of sediments that are stirred up by the bubbles and also to help the diffuser lay flat on the bottom and the plate can be used to stabilize the diffuser by adding a rock or weight to keep the stick in place. Includes 3/8" barbed hose adaptor to fit the 3/4" MPT inlet..

For maximum fine-bubble aeration the dual-stick KoiAir™ PTFE weighted diffuser is the way to go. The two sticks are attached to a heavy duty polyplastic base to reduce the amount of sediments that are stirred up by the bubbles and also to help the diffuser lay flat on the bottom and the plate can be used to stabilize the diffuser by adding a rock or weight to keep the stick in place. Includes 3/8" barbed hose adaptor to fit the 3/4" MPT on the inlet..
